To al whom z't may concern: e

Be it knownthat I, ITALO ALFRED DE POLO, a. citizen Vof the United States, residing at Connellsville, in the county of Fayette, State of Pennsylvania, have invented a new and useful Screening and Separating Machine;

and I do hereby declare the following to be a full, clear, and exact description of the inventiOn, such as will enable others skilled in the art to which it appertains to make and use'the' same.

This invention relates to an 4improved screening and separatingmachine, 'particu-- larly designed for use for screening or separating ashes, coal and the like1 and one of the objects of the invention is to provide a wheel supported portable frame, and a super-im posed frame, and means Yfor revolving said super-imposed frame.

A further object of the invention is to provide meansfor diggingthe coal and ashes or the like, elevating the same and screening means adjacent the upper end ofthe elevating mea-ns, all of which being carried by 'and mounted on said super-imposed revolving framel A further object `of the invention is the provision of -power means on the revolving frame for operating the various mechanisms carried thereby.

A further' object of the invention is the provision of improved means connecting with the power means and a gear on the revolving frame, for revolving the frame at will in different directions.

In practical fields the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts as hereinafter set forth shown in the drawings-and claimed.

In the drawings i Figure 1 is a view in side elevation of the screening and separating machine constructed in accordance with the invention.

Referring more especially to the drawings 1 designates the platform or bedplate of the'A portable frame, and which bedplate or platform is mounted'upon the forward and-rear supporting wheels 2 and 3. The forward wheels 2 are mounted upon the front axle 4;, the bolster 5 of which is pivotally connected Aat G by a king pin to the bolster '7, whereby vthe forward wheels may be, turned in one direction or the other-for steering the machine from one place to another. Project, i ing downwardly from the platform or bedplate 1 or frame from each side portion-sulV stantially midway the ends of the frame 1 are brackets 8, which are substantially T- shaped and'have their arms 9 secured at 10 to said frame. Brace rods l1 engage the 'icrotches or notches 12 of the/brackets 8,

and the ends of said rodspass upwardly lthrough the frame 1 and have nuts 13' f threaded thereon for holding the rods se-4 cure, and consequently bracing ftheframe.

Mounted in suitable bearings 14 ofthe frame l is a shaft 15, on which the drums 16 are vmounted to rotate with the shaft. Suitable cables 17 are wound about the drums and have their ends secured at 18 to' the drums. The other ends of the cables 173are connected at 19 to the bolster 5 of"t he,front axle. A hand wheel 2O is'keyed lfyjine'ians of a pin 21 to oneend of the shaft 15, so

that by rotating the wheel 20 in' onev direr.-

tion or the other, the cables 17 (which arev wound in opposite directions on thefd'rums) may be so operated to oscillate the axle 4,

to swing the front wheels, whereby the mau chine may be guided to the right or the left.

Mounted upon thev be'd frame or plate 1,

forwardly, rearwardly and near the sides thereof are plates 22, 23 and 24, which may be secured in any suitable manner as shown at 25.` Ihese plates are provided with elon-l gated pockets 26. which longitudinally and in cross section, as shown are` of the shape clearly in Figs. 5 and 6. and are designed to receive the roller bearings 27. 28 and29. It is to be noted, however` I are connected by the flanges 30,` which. are secured as at 31 to the longitudinal edges of the base pla-te or frame 1. A frame 32 is superimposed on the -frame,1, and comprises the forward and rear corner upright beams 33 and 34 and the side upright beams 35, ally of which are mounted upon the base or plat-r form 36. This superimposed frame 32 is that the plates 24@k movable to spring about a vertical axis, in

fact the frame may be osellated or revolved in either direction of said vertical axis. The forward upright beams 33 have their upper ends braced relative to each other by the beams 37, and the upper ends of the rear upright beams 34 are likewise braced by the beam 38. The longitudinal beams 39 connect the forward and rear upright beams 33 and 34, there being additional braces 40 for reinforcing the structure of the frame 32. The bSe 36 of the frame 32 is suitably cutaway to provide the openings 41, to lighten Said base. The frame 32 carries storage and delivering bins 42 and 43. Each bin is provided with an upwardly extending V-shaped bottom 44, as shown clearly in Fig. 4, and also the forward and rear inclined plates 45. By these inclined plates and the inclined sides of the V-shaped bottom, the material falling in the hoppers is divided toward each side and will easily empty from the openings 46, which are closed bythe doors or closures 47 hinged at 48. The sides of the bin 42 extend completely to the top of the frame 32. The base 36 of the frame 32 at its forward ends on its bottom is provided With bearing plates 49 the ends of which are bent and Secured at 50 to the edges of the base 36. These plates 49 engage the roller bearings 27 and 28. Secured by the Screws 51 to the sides of the base 36 are the angle plates 52, which extend under the base 36 and engage the roller bearings 29. Arranged centrally of the base or frame 1 is a circular plate 53, which is secured by the screws 54 to the frame 1. This circular plate 53 is provided with radial pockets 55 for the reception of the roller bearings 56. Arranged on the top of the base 36 and centrally thereof is a bevel gear 57 provided with a ange 58. A bearing` plate 59 is arranged on the under surface of the base 36 and centrally thereof, so as to engage the bearing rollers 56. Suitable fastening means or bolts 60 pass through the flange 58, the base 36 and the bearingr plate 59 for securing said parts together. A bolt 61 passes through the gear 57, the base 36 through the circular plates 53 and 59, and through the base or frame 1, and is provided with a. nut 62, whereby said parts are united, so that the frame may revolve on the frame 1` Mounted in suitable bearings 63 vof the base 36 iS a shaft 64 on one end of which a beveled gear 65 is fixed so as lo mesh with the bevel gear 57. Keyed by means ol a feather 66 on the shaft 64 is a sleeve 67 and formed integral with the ends of this sleeve are bevel gear flanges or collars 68 and 69. One end portion ot the sleeve 67 has an annular groove 70, in which the slip ring 71 is mounted. A lever, which is pivoted at 72 to the base 36, has ils forks l73 connected to the pins 74 of the slip ring or collar by means of the slots 75. A shaft 76 is mounted in bearings 7 7 of the base 36 and has fixed thereto a double bevel gear 78. A pulley 79 also keyed to the shaft 76 to be engaged by the belt 80. When power is furnished to the double bevel gear 78 through the medium of said belt 80, and when one or the other of the bevel gear hollows or branches 68 and 69 is in mesh with the gear 78 by operating the lever 81, which is pivoted at 72, motion is imparted lo the Shaft 64.

ing with the gear, 57 the frame 32 may be revolved in one direction or the other. A shaft 82 is mounted in bearings 83 of the frame 32, and fixed on the shaft 82 are pulleys 84 and 85. The belt 80 passes about the pulley 84, and a belt 86 passes about the pulley 85. A suitable motor 87 is mounted on the forward end portions of the base 36, and its shaft carries a pulley 88, about which the belt 86 passes, thereby providing power for the shaft 82 which in turn fur nishes power, whereby the frame 32 may be revolved in one direction or the other. A suitable conveyer frame 89 arranged on an incline is carried by the frame 32. The upper and lower ends of the conveyer frame rcspectively have shafts 90 and 91, provided with sprockets 92 and 93 about which the conveyer Sprocket chain 94 passes. This conveyer sprocket chain is provided with conveyer buckets 95. The lower end of the conveyer fraaie 89 carries a suitable digger 96, similar to that set forth and illustrated in the application for a patent on a screening and separating machine, Serial Number 188.641, tiled Aug. 28, 1917, in the name of I. A. De Polo. his digger and thc, conveyer combined constitute a mechanism, adapted to be directed. to lrather or collect material and deliver thc saine lo a combined agitator and screening device, to be hcrcinafter set forth. Also mounted in the conveyor frame 89 (which is reinforced relative to the frame 32 by the braces 97) is a sha'l't 98, provided with the sl'irockcts 99 and lrlll. A Sprocket chain 10i (which engages and passes about the sprockets 102 on the sl-fIl't 82) passes about thc ,sprocket 100. ()n thc ends of the shaft, 90 are sprockcts 103 and 104. A sprocket chain 1.05 passes aboul the sprocket 104 and the sprocket 9,9. and since (he shaft 812 is driven by the motor` it is to be observed that the elevating couvcycr 94 is driven by the sprocket chains |01 and 105 and their connections. Mounted in bearings 106 on the top ot' the l'rame 32.

Since the gear 65 is mesi ing into Jthe hopper or bin 42, the cinders or the-targa partlcles of tliecoal orthe like passing out the end 109 of the drum into the hopper or bin 43. (me end of the shaft 107 has a bevel gear l10. `Mounted in a bearing 111 ofthe top of (he frame 32 is a shaft 112 provided with a beveled gear 113 and a Sprocket 114; A sprocket chain 115. passes about the sprocket 114 and the sprocket 103, in view of which it will be seen that. most motion is imparted to the screening drum receiving power 'from its connection with the upper shaft of the elevating conveyor., which in turn is driven by the shaft 82.` The digging device, the ele vat-ing conveying means, the screening mecl1- anism and the-hopper arrangement are all similar to the corresponding parts set forth and illustratedin the aforesaid pending application.

In the operation it is to be seen that by the provision of the belting or gearing between the driving motor with the vertical axis of the movable frame, and the clutch connections, said movable frame may be easily and at will controlled. whereby said gathering and delivering mechanism may be directed toward different points or places of a dump. In fact the frame may be involved entirely about its axis. By this construction the gathering and delivering mechanism may be moved to the rear part of the `main frame, without turning the entire main frame about or backing it from the dump,

so as to direct the digger to the rear part of the side of the dump. For eirample in operating this machine, the operators may direct4 the machine, so as to make or wedge a cut into the dump of coal ashes or coke ashes, and instead of backing the machine out from thc cut entirely, it may be backed a short distance, then i'noved forwardly, and the movable frame swung entirely at right angles to the wheeled tran-1e, and then `the digger or gathering mechanism may operate on the side of the cut in the dump. This gathering and delivering n'iechanism delivers the material to the combined agitator and screening device or drum, where it is agitated and screened into two different grades,

separately delivered into the storage and delivering bins 42 and 43 respectivelv.A

bins mounted upon The invention having been set `forth what is claimed as new and useful is 1.
